Unlike much of the ransomware we've written about in the past, CryptoLocker doesn't attempt to use police themed trickery or other sleight of hand. It's strictly business. It infects via e-mail attachments (zip files containing supposed PDF files) and then sets about encrypting all of your personal data files — photos, music, documents, et cetera.

It's largely a problem in English-speaking countries because that's the language used in the e-mail bait. For now. It's certainly only a matter of time because somebody decides to expand into other languages.

That's right, CryptoLocker accepts everybody's favorite cryptocurrency as payment. And that's why this could be a tipping point. One of the biggest factors keeping ransomware at bay is the difficulty it takes to get paid. Thanks to Bitcoin and other similar digital currencies… that barrier is eroding fast.

Ransomware economics: the more frictionless Bitcoin becomes — the more prevalent CryptoLocker will become.
